Hab, — Goruckpore, Capt. Vicary ? 



Descr. — Sesquipedalis. Radices testiculatse. Folia sub- 

 carnosa, subtus carinata, glabra, summa in folia floralia acu- 

 minatissima mutata. Spica elongata, densiflora. Bracteae 

 acuminatae, ascendentes, ovariis breviores, vel interdum subae- 

 quantes. Flores parvi, inconspicui, viridescentes. Sepala 

 oblonga; posticum cum petalis galeam efFormantia ; lateralia 

 patentia, Labelli lobi laterales centrali obtuse fere triplo 

 angustiores, oblique penduli. Calcar ovario 1 J longius, pen- 

 dulum. Stamina sterilia anthera breviora. Antherae loculi 

 basi parum producti. Stigma posticum abbreviatum ; lateralia 

 dua in fauce calcaris recondita, ratione prascedentis obsoleta. 



This species, vi^hich belongs to the section Rostratse of 

 Dr. 'Lindley^s genera and species of Orchidaceous Plants, 

 appears to approach H. commelinifolia. It differs, how- 

 ever, abundantly by its smaller greenish flowers, the shorter 

 rostrum of the ovarium, the spreading (not reflexed) almost 

 equilateral sepals, the three-lobed labellum, and generally in 

 the small comparative development of the stigmatic processes, 

 and shortness of the bases of the anther cells. 



It was introduced by Capt. Vicary, I am told, from Go- 

 ruckpore. It flowers here in August and September. It 

 seems to vary somewhat in the divisions of the labellum 

 and length of the spur.* 



* To these Habenarise I subjoin an account of H. marginata, another 

 Bengal species, and of a Bengal species of Bonatea. 



H. marginata Coleb, foliis humifusis approximatis oblongis basi cor- 

 datis albomarginatis, racemo oblongo brevi paucifloro, labelli profunde 

 tripartiti laciniis lateralibus plano-subulatis curvatis centrali porrecta 

 sublanceolata longioribus, sepalis lateralibus basi angustata cum labello 

 connatis, calcare pendulo clavato apice ventricoso ovarii longitudine.
